This is the first time this has happened to me, so I got excited about it until I noticed that this command has been with us from nearly the very beginning (ie MySQL 4).
The Situation
Master Server contains db1
Slave Server contains db1 and db2
Slave Server needs db1 from the Master to replicate to db2
The Solution
On my.cnf on the slave server:
--replicate-rewrite-db=from_name->to_name
